May I suggest a "King of the Hill" gamemode? It's kinda simple: The team who can keep the control point captured for 3 minutes wins the game. The other team can capture it by standing on it for... let's say 10 seconds? There's a timer for each team. The control point can be anything. I don't know if it's just be, but I'd really love to see and play KOTH on JJ2.
